Exclamation no crank no start. ANY ADVICE !?

Been having electrical problems since last July, i changed the bcm today, had it programmed with the tech 2, then tried to re learn the theft deterrant system and it wont with a tech2, tried manual relearn, it locks the truck up after the first cycle out of three. Swapping out ecm tomorrow to see if i can even get the truck to crank.

v2 or tech 2 wil communicate now.

Any body help or have any suggestions??

I know the duramax community is usually pretty tight, but its like when i ask for help on this topic i might as well have chugged a fifth of jack at an AA meeting.

hopefully somebody can help.

I don't know if this would even cause this much problems, but have you checked the wire loom that is zip tied to the altenator bracket. I know if it rubbs through and those wires break or ground out, it can cause some strange problems.

Sometimes they get a short under the hood fuse box. The wires rub against the support brackets.

Of course the NSBU switch can always be a problem with the LLY. But without communication-- that cannot be the issue.

Some do have ignition switch problems-- but easy to check with a test light or volt meter.

Good luck

Can't read codes, won't communicate. Swapping ECMs now to see if it cranks at all
